Description
Technical Field
The application relates to the technical field of plastic processing, in particular to a plastic compatilizer composition, a thermoplastic recycled plastic and a processing method of the thermoplastic recycled plastic.
Background
Plastics are important derivatives in petrochemical industry. With the shortage of global petroleum resources, recycling of plastics has become an important issue. In the prior art, the method of melting and extruding the crushed old plastic and the newly produced plastic master batch together is often adopted to process the regenerated plastic, so as to recycle the plastic waste.
Because the polymer molecules of the plastic are aged with time or in the sun during use, the compatibility between the recycled and re-pulverized recycled plastic particles and the newly-formed plastic master batch is poor, so that yellow spots often appear in the produced recycled plastic, and the strength of the plastic is adversely affected. In order to solve the above problems, it is often necessary to add a compatibilizer to the plastic to make the two plastic particles have better compatibility, so as to form a more uniform plastic system, reduce the occurrence of yellow spots on the regenerated plastic, and improve the uniformity of the plastic. A preparation method of a compatilizer is disclosed in Chinese patent with an authorization publication number of CN101469071B and an authorization publication date of 2011, 6, month and 22, and comprises the steps of taking a copolymer of styrene and maleic anhydride as a macromolecular activator, adding 1-30% of maleic anhydride by mass, adding lactam to enable the mass ratio of the copolymer to the lactam to be 1-50: 99-50, forming a homogeneous solution at 120-250 ℃, adding an initiator to prepare a graft copolymer of the copolymer and nylon through anionic ring-opening polymerization, and taking the graft copolymer as the compatilizer between the styrene polymer and the nylon.
In the prior art, a polymerization system of maleic anhydride and styrene is used as a compatilizer, and the strong polarity of the maleic anhydride can attract polar groups such as oxidized peroxy groups and hydroxyl groups in the recycled plastic particles mutually, so that the recycled plastic particles and the newly produced plastic master batch are melted and then uniformly mixed. However, if the polar group contained in the recycled plastic is small, the compatibilizing effect by the compatibilizing agent is not preferable.
Disclosure of Invention
Aiming at the defects in the prior art, the first invention of the application aims to provide a plastic compatilizer composition which has better compatibility for plastics containing polar groups and plastics containing nonpolar groups and can improve the uniformity of the recycled plastic particles and the plastic master batches during mixing and melting when the plastics are recycled.
The second invention of the present application aims to provide a thermoplastic recycled plastic, which can realize the recycling of plastic waste, wherein the plastic waste particles and the plastic master batch are uniformly mixed, the yellow spots on the surface after molding are less, and the strength is higher.
The third object of the present invention is to provide the above method for processing a thermoplastic recycled plastic, which can fully exert the effect of the compatibilizer in the compatibility of the plastic.
The above object of the present application is achieved by the following technical solutions: the plastic compatilizer composition comprises the following components in parts by mass:
maleic anhydride-modified polymer: 80-120 parts of a solvent;
butadiene-based thermoplastic elastomer: 60-95 parts;
talc powder: 15-22 parts;
wherein the maximum particle size of the talcum powder is less than or equal to 10 mu m.
In the technical scheme, the butadiene thermoplastic elastomer and the talcum powder are added on the basis of the maleic anhydride modified polymer, wherein the butadiene thermoplastic elastomer has good compatibility with a nonpolar high polymer and can act together with the maleic anhydride modified polymer to uniformly mix the recycled plastic particles with the plastic master batch in the melting process, so that the uniformity of the plastic is higher.
The talcum powder can reduce the viscosity of the butadiene thermoplastic elastomer and is beneficial to more uniformly dispersing the butadiene thermoplastic elastomer in the melted recycled plastic particles and plastic master batches in the melting process, so that the plastic compatilizer composition can be more effectively and uniformly dispersed in a melted plastic system in the using process, and the plastic is more uniform integrally.
By comprehensively using the maleic anhydride modified polymer, the thermoplastic elastomer and the talcum powder, the plastic compatilizer composition can improve the mixing uniformity of the plastic master batch and the recycled plastic particles during melting regardless of being used in the plastic containing polar groups or the plastic without polar groups, thereby reducing the uneven structure in the plastic, reducing the yellow spots in the processed plastic and improving the strength of the prepared plastic product.
The present application may be further configured in a preferred example to: the maleic anhydride modified polymer is a copolymer formed by grafting maleic anhydride on low-density polyethylene.
The low-density polyethylene has more branched chain structures, so that the overall structure is looser after the low-density polyethylene is grafted with maleic anhydride, and the branched chain structures in the low-density polyethylene after being thermally melted can form a winding structure with the plastic master batches and high polymers in a system after the plastic master batches and the recycled plastic particles are melted, thereby being beneficial to further improving the strength of the processed plastic.
The present application may be further configured in a preferred example to: the plastic compatilizer composition also comprises 33-50 parts by mass of alkyl cellulose ether.
The alkyl cellulose ether is a long-chain polymer substance and has good solubility in water and organic solvents. Because the high molecular chain of the high molecular component in the plastic is easy to break after long-term use, after the alkyl cellulose ether is added, the alkyl cellulose ether can be acted with the butadiene thermoplastic elastomer to connect and recycle the broken polymer in the plastic particles, thereby improving the strength of the processed plastic. In addition, the alkyl cellulose ether may also be
The present application may be further configured in a preferred example to: the plastic compatilizer composition also comprises 7-10 parts by mass of a nonionic surfactant.
After the surfactant is added into the plastic compatilizer composition, the surfactant can enable the cellulose ether to be more uniformly dispersed in molten plastic when the plastic is produced, so that the cellulose ether is more uniformly dispersed in the plastic, the uneven structure generated in the plastic is reduced, and the strength of the produced plastic is improved.
The present application may be further configured in a preferred example to: the plastic compatilizer composition further comprises 5-8 parts by mass of a first antioxidant, and the first antioxidant is a phosphite antioxidant.
Since both the butadiene-based thermoplastic elastomer and the maleic anhydride-modified polymer are easily oxidized in the air, in the above-mentioned technique, the addition of the first antioxidant to the plastic compatibilizer composition can extend the service life and shelf life of the compatibilizer composition.
The second invention purpose of this application is realized through following technical scheme: the thermoplastic recycled plastic comprises the following components in parts by mass:
plastic master batch: 1000-1400 parts;
and (3) recovering plastic particles: 400-1000 parts;
plastic compatibilizer composition: 100-200 parts;
40-60 parts of an ultraviolet absorbent;
silane coupling agent: 0-130 parts;
wherein the plastic compatibilizer composition is the plastic compatibilizer composition according to any one of claims 1 to 6.
In the process of melting and extruding the plastic master batch, the recycled plastic particles and the plastic compatilizer composition together, the plastic compatilizer composition can improve the distribution uniformity of the recycled plastic particles in molten plastic, so that the plastic is more uniform as a whole, yellow spots generated by agglomeration of the recycled plastic particles in the melting process are reduced, and the strength of the thermoplastic recycled plastic obtained by processing is improved. The ultraviolet absorbent can prolong the service life of the thermoplastic regenerated plastic by absorbing ultraviolet rays. The silane coupling agent can act together with the talcum powder to connect the talcum powder and the macromolecular chains in the molten plastic, so that the effect of improving the strength of the thermoplastic regenerated plastic is achieved.
The present application may be further configured in a preferred example to: the adding amount of the silane coupling agent is 50-80 parts.
By limiting the adding amount of the silane coupling agent to 50-80 parts, the surface of the talcum powder can be more easily coupled with the silane coupling agent, and the amount of the silane coupling agent coupled on the surface of the talcum powder is limited, so that the talcum powder is not easily connected with each other, the distribution uniformity of the talcum powder in molten plastic is more favorably improved, and the integral uniformity and strength of the plastic are further improved.
The present application may be further configured in a preferred example to: the plastic master batch is at least one of PE or PET, and the recycled plastic particles are at least one of PE or PET.
PE and PET are two kinds of thermoplastic plastics which are widely used at present, wherein PE is commonly used in various pipes, building materials and film products, and PET is commonly used for manufacturing plastic bottles, plastic bottle caps, workpiece shells, pipe connectors and other products. In daily life, the waste materials of the plastic products are wide in source and large in consumption, so that the PE and the PET are used as raw materials, the production cost is reduced, and the economic effect is improved.

In the above steps, the stirring speed in step S2 is fast, which is helpful for further fusing the recycled plastic particles and the plastic master batches after melting, so that the overall structure of the plastic is more uniform, and the strength of the molded plastic is improved. In step S3, the stirring speed is slow, so that the long fiber structure to be molded is not easily broken, which contributes to higher strength of the plastic after molding.

Firstly, mixing the plastic compatilizer composition and the ultraviolet absorbent with the plastic master batch and the regenerated plastic master batch, then heating the whole system to 220 ℃, and stirring for 10min at the speed of 1.2 r/s.
Comparative examples 4 to 6, thermoplastic recycled plastics, are different from example 18 in that the plastic compatibilizer compositions used were the plastic compatibilizer compositions of comparative examples 1 to 3, respectively.
Comparative example 7, a thermoplastic recycled plastic, differs from example 18 in that the stirring speed was 2.4r/S in both step S2 and step S3.
Comparative example 8: a thermoplastic recycled plastic, which differs from example 18 in that no compatibilizer composition was added to the plastic.
The physical and chemical properties of the above examples and comparative examples were measured by the following experiments.
Experiment 1: in a plastic tensile strength test, the tensile strength of the thermoplastic recycled plastics prepared in examples 18 to 46 and comparative examples 4 to 8 is measured according to the detection method in GB/T1040.1 to 2018.
Experiment 2: and (5) observing the surface topography of the plastic, and observing whether the yellow spots exist on the surface of the plastic.
The experimental results of examples 18 to 46 and comparative examples 5 to 8 are shown in Table 3.
Table 3: experimental data lists for examples 18-29 and ratios 4-8
The tensile strength of common polyethylene plastic is about 40MPa, and the tensile strength of polyethylene terephthalate is about 55 MPa. In general, after a plastic is used for a long time, free radicals are generated under the action of oxygen and ultraviolet rays in the air, so that long chains in the plastic are broken. And after the thermoplastic plastic is heated and re-solidified, molecules can be wound and crosslinked, and small molecular groups are easily formed in the crushing process, so that as shown in comparative example 8, when the plastic is recycled, the old plastic is often difficult to be well mixed with newly prepared plastic master batches, the integral strength of the plastic is not high, and yellow spots are generated on the surface of the plastic. In the embodiments 18 to 23, polyethylene and polyethylene terephthalate with different proportions are respectively selected, and the plastic compatilizer composition obtained in the embodiment 1 is added, so that the strength of the prepared plastic is better than a theoretical value, no yellow spots appear on the surface, and the effect of improving the plastic compatilizer composition is proved. In addition, in comparative example 4 and comparative example 5, compared with example 18, talc and a butadiene-based thermoplastic elastomer were not present in the plastic compatibilizer, and it is clear from the data that the compatibility effect was poor, and uniform mixing of the recycled plastic particles and the plastic master batch after melting could not be achieved, resulting in a decrease in strength of the plastic and the appearance of yellow spots.
In examples 24 to 27, compared to example 18, the silane coupling agent is added to modify the talc powder, so that the talc powder can be more uniformly distributed in the molten plastic, and the plastic polymer and the talc powder form a closer connection relationship, thereby further improving the tensile strength of the molded thermoplastic recycled plastic. Among them, examples 24 and 25 have a better strength-improving effect than examples 26 and 27. Examples 28 and 29, the proportions of the individual components are adjusted, which has a pronounced effect on the strength and surface morphology of the thermoplastic recyclates.
In comparative example 6, the talc particles were too large, which adversely affected the strength of the molded thermoplastic recycled plastic. In comparative example 7, the stirring speed in step S3 was too high, resulting in that the polymer fibers formed by the reconnection of the plastic compatibilizer composition were easily broken during the stirring, and the resulting plastic was poor in strength.
The experimental results of examples 30 to 46 are shown in Table 4.
Table 4: experimental data lists for examples 18-29 and ratios 4-8
In examples 30 to 39, the plastic compatibilizer compositions obtained in examples 2 to 11 were used. The plastic compatilizer compositions of examples 4-6 and 10-11 are added with alkyl cellulose ether, the nonionic surfactant is added in examples 6-7 and 10, the antioxidant is added in examples 8-11, and the addition of the above materials improves the strength of the prepared thermoplastic regenerated plastic. The principle of the method is that the cellulose ether can play a role in supplementing long chains, and simultaneously can act together with the butadiene thermoplastic elastomer to form a more complex winding structure with a plastic macromolecule, so that the strength of the prepared plastic is improved. The surfactant can reduce the hydrophilicity of the alkyl cellulose ether, so that the alkyl cellulose ether is dispersed in the plastic more uniformly, the integral uniformity of the plastic is improved, and the strength of the prepared thermoplastic regenerated plastic is improved. The antioxidant may then serve to protect the plastic compatibilizer combination.
In examples 40 to 45, the plastic compatibilizer compositions of examples 12 to 17 were used, and the types of the alkyl cellulose ether, the nonionic surfactant and the first antioxidant were changed in examples 12 to 15, respectively, and it is understood from the data that the change of the above materials did not significantly affect the strength of the thermoplastic recycled plastics obtained in examples 40 to 43. Examples 16 and 17, corresponding to examples 44 and 45, replace the maleic anhydride grafted low density polyethylene with maleic anhydride grafted high density polyethylene and maleic anhydride grafted styrene, respectively, resulting in a slight decrease in the strength of the thermoplastic recyclates prepared in examples 44 and 45. The principle of the method is that the low-density polyethylene has more branched chain structures, is easy to form a winding structure with other high molecular substances in a system, and can further improve the strength of the plastic after hot melting extrusion. In example 46, the plastic compatibilizer composition and the ultraviolet absorber were directly mixed with the plastic master batch and the plastic recycled master batch and then melted and heated, and the heating process may adversely affect the components in the plastic compatibilizer composition, thereby resulting in a decrease in the strength of the resulting thermoplastic recycled plastic.
In conclusion, the plastic compatilizer composition formed by matching the maleic anhydride modified polyethylene, the talcum powder and the butadiene thermoplastic elastomer can effectively improve the strength of the plastic and reduce yellow spots on the surface of the plastic in the process of preparing the thermoplastic recycled plastic.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the scheme and the principle of the application are covered in the protection scope of the application.
